Definitions

  • the invention relates to a snowboard having a front end, a rear end and a waist region located between front end and rear end, in which a front binding region and a rear binding region spaced therefrom by a central region are arranged, wherein the waist region in the front binding region and in the rear binding region - in plan view of the snowboard - has concave side edges.
  • the present invention has for its object to provide a snowboard, which has excellent handling characteristics, in particular Fahrêtverzeihend and easy to turn and controllable to drive, but it offers excellent edge retention and directional stability.
  • a snowboard with a front end (English: nose), a tail (English: tail) and lying between the front end and rear end waist side (English: sidecut), in which a front binding area (English: leading binding area) and one of which is arranged by a middle region spaced trailing binding area (English: trailing binding area), wherein the waistband in the front binding area and in the rear binding area - in plan view of the snowboard - has concave side edges.
  • a convex bulge is provided in the front binding area and in the rear binding area on the right and the left side.
  • convex protuberances make contact points between the snowboard and the ground, ie snow or ice, which, by their specific positioning, allow a more direct transmission of the kinetic energy of the snowboard rider to the ground.
  • the rider has optimal control over the snowboard, as his movements are transmitted over the shortest distance over the feet and the binding to the ground and the "feedback" of the snowboard or
  • the driver is able to activate the contact points provided by the convex bulges in two different ways: on the one hand, by placing the snowboard on the ground On the other hand, it makes use of the existing longitudinal flexibility of the snowboard and moves its feet against each other so as to activate either a contact point in the front binding area or a contact point in the rear binding area.

  • the driving and control properties of the snowboard according to the invention are further improved if the radii of the convex protrusions are smaller than the smallest radius of the concave side edges, preferably if the ratio of the radii of the convex protrusions to those adjacent to the convex protrusions Radii of the concave side edges is between 1: 5 and 1: 2, preferably between 1: 4 and 1: 2.5.
  • Modern snowboards offer the possibility of variability of bond mounting within the respective bond areas, eg by providing two parallel rows of holes for receiving mounting screws.
  • This variability of the binding assembly is also provided in the snowboard according to the invention. It has been recognized in one aspect of the invention that optimum energy transfer and controllability of the snowboard according to the invention is achieved when the maximum bulges of the convex protrusions at reference binding positions (English: reference stance) lie in the front binding area and in the rear binding area. Good tracking is achieved in a variant of the snowboard according to the invention, when the sidecut area, apart from the convex bulges, over its entire length continuous concave side edges.

That is, the curvature of the negative bias is in the middle of the snowboard - and thus between the rider's feet - more pronounced and progressively decreases towards the ends.
  • This snowboard geometry slightly raises the contact points to the ground. This gives the driver a sense of independence on the snowboard, which is subjectively comparable to the driving experience on a skateboard.
  • the snowboard geometry of the present invention facilitates facilitated initiation of so-called "ollie jumps.”
  • Another advantage of the snowboard of the present invention is that it can be made stiffer compared to conventional snowboards without the rider feeling the stiffness subjective.
